Which one is the o2 sensor before the precats? Is that the one that supposed to give me 0.86V and up? Thats an average, correct?

When the secondaries open there is a bump in the torque horsepower. There also is a bump in the air fuel being that there is more air rushing in. This is how I gauge the speed. It is about 200rpm off. I also found out that some sniffers can add air and throw it off an extra 1000 rpms. If it's true that we are here to help others, then what exactly are the others here for?
